3.2. Sugar yield
For poplar wood particles cut from Orientation L, sugar yield
decreased as the depth of cut increased. Sugar yields were 1.5 g/L
(0.07 g/g biomass), 1.0 g/L (0.05 g/g biomass), and 0.8 g/L
(0.04 g/g biomass) for particles cut from Orientation L with depths
of cut of 0.1, 0.25, and 0.4 inches, respectively. Depth of cut used in
size reduction primarily determined thickness of the produced particles.
Smaller depth of cut produced thinner particles. In general,
wood particles cut from Orientation R had higher sugar yield than
particles cut from the other two orientations. Particles cut from
Orientation R with a depth of cut of 0.25 inch produced the highest
sugar yield of 2.0 g/L (0.10 g/g biomass), while particles cut from
Orientation R with a depth of cut of 0.1 inch had a slightly lower
sugar yield of 1.8 g/L (0.09 g/g biomass). Particles cut from
Orientation T with depths of cut of 0.1, 0.25, and 0.4 inches had
sugar yield of approximately 1.3 g/L (0.06 g/g biomass), and the
difference among sugar yields in Orientation T were not significant
as depth of cut increased.
